What Is Cationic Polyester Yarn? Cationic Dyed Polyester Yarn-full name: cationic dyed polyester is called cationic dyeable polyester, which belongs to denatured polyester and can be dyed with cationic dyes at 110 degrees. Cationic yarn belongs to modified polyester, chemical name: polybutylene terephthalate (elastic polyester), abbreviation: PBT, and it is also represented by CD in the factory. Because ordinary polyester (polyethylene terephthalate) has disadvantages such as low moisture absorption, poor dyeing performance, easy accumulation of static electricity, and easy fluffing, etc., it is usually modified with sulfonate as a modifier to be dyeable with cationic dyes. Modified polyester is prepared by adding cationic active agent before spinning or during the spinning process. Such yarn is called cationic yarn. This kind of yarn does not need to be dyed at high temperature like ordinary polyester, and can be dyed at room temperature. Cationic modified polyester filament is a new type of polyester product spun by introducing dimethyl isophthalate with polar group SO 3Na into polyester chips.
